Summer capacity management in El Yunque National Forest in July to include the pilot phase of a tram system
As part of the traffic control operation, when parking spaces in El Yunque are filled, the gate at La Coca Falls on Rd 191 at Km 8.1 will be closed until it is safe to allow additional traffic to enter the Forest. On peak visitation days, visitors are advised to arrive early in the day to be most successful in finding available parking spaces. The Forest will continue to use intelligent traffic systems including electronic signs and the AM radio station 1710 to continuously inform the public of updates related to parking capacity or Forest closures.
Traffic control operations will be in effect during holidays of July 4-7, July 13-15 and July 25-29. There will also be stand-by traffic control operations for other days during the summer to help manage parking capacity situations as needed.
Starting in July, the Forest Service intends to begin the pilot phase of a tram system. The Municipality of Rio Grande, will be operating a specially designed tram units to move visitors about Forest recreation areas during peak summer visitation days. At this time, the tram will circulate only between Yokahu Tower and Mt Britton trailhead in the main recreation area and are tentatively scheduled to operate from Wednesday to Sunday at no charge to visitors. While the tram is operating, other vehicles will be able to operate in the Forest. Testing of the tram units to determine operations and schedules continues during June.
